Um ET is the only way to clear VM since.... a long time? Ok not the only way, I think red matter thingy works to. Maybe I missed something but it was like that for months.

No, so far ET would repair the currently disabled subsystem caused by VM, so does EPtX, Batteries, MW, and according to tooltip RMC (its broken). HOwever, VM would continue to cycle through the remaining subsystems.

The new version of ET, clears VM outright, so you restore the currently disabled subsystem, and no other susbsystems will become disabled. VM is gone.
